Recently, a group of scientists issued a statement that up to 40 percent of people infected with parasites of the brain, which may affect the behavior of the person.
Professor of Epidemiology at Imperial College London, John Webster explains this by saying that in the brain parasites are isolated and protected from attack by the immune system. According to him, it also gives them the opportunity to influence human behavior.
Often occurring in domestic cats celled parasite Toxoplasma can infect the year 350,000 Britons. Professor of evolutionary biology at Prague's Charles University Jaroslav Flegrei connects the impact of Toxoplasma with a penchant for sloppy driving and suicide.
A study by scientists at Imperial College study concluded that Toxoplasma-infected mice did not put, on the contrary, attracted by the smell of cat urine.
Presented in the form of microscopic cysts Toxoplasma was found in two areas of the brain: in charge of fear and pleasure. Repulsive reaction to the smell of cat urine was reduced, and the increased concentrations of the hormone dopamine, normally produced in the rodent back by the smell of urine of females was caused by a launch on the cat's scent. Recent studies have also shown that the DNA of Toxoplasma include two gene increases the production of dopamine. The similarity of the structure of human brain and rodent brain suggests that the majority of road accidents Toxoplasma infected could be caused by dulling fear.
Scientists believe that 40% of the UK population may be infected with Toxoplasma. However, despite the fact that their studies are directly related to the population of the United Kingdom, the parasite is so prevalent around the world, 40 percent of these may relate to the people around the globe.
In another study, headed by Dr. Barragan and conducted in collaboration with researchers at Uppsala University, has been published in the scientific journal PloS Pathogens.V a recent interview, Dr. Barragan was stated that the problem of Toxoplasma infection is not new to mankind:
We believe this knowledge is important for the further understanding of some of the major issues in health care, for which modern science can not answer … At the same time it is important to emphasize that the people were living with Toxoplasma for thousands of years, so it is not a cause for concern modern carriers of the parasite.
We did not examine behavioral changes of infected people, as they have been mentioned in previous studies. Instead, we discovered mechanisms parasite penetration into the brain, and manipulate the carrier.
The main goal of the research is to understand the mechanisms of the brain neurotransmitter messages between themselves, and the results are likely to be used in the development of psychiatric drugs.
Although an idea and understanding of the mechanisms and functions of the human body is useful, it is important to follow the course of these studies, in order to exclude the possibility of their use with the intent to control the population.
Regarding the parasite itself, in most cases it is safe, except that might make you a little crazy, but we all have to some degree a little dippy, so it does not really matter.
